SANITARY SELF-SEALING TMP.

Specification of Letters Patent.

Patented Dec.. 2, 191m.

Application led July 8; 1919. Serial No. 309,495.

To all lwhom t may concern: Be it known that l, HARRY C. ODnnKmK, citizen of the United States, residing at Cleveland, in the `county of Cuyahoga and State of Chio, have invented certain new and useful Improvements in Sanitary Self- Sealing Traps, of which the following is a specification. l

My invention relates to a sanitary selfsealing trap especially designed for use in connection with bath tub waste drainage.'

The `prime object of this invention is to provide a sim 1 le, economical, durable and thoroughl 'elicient sanitary self-sealing trap, pre erably of the drum type of construction, suitably connected to the waste pipe of a bath tub. l

A further objectof the invention is to so construct my improved trap as to dispense body, thus permitting it to be` readilyl cleaned; both the inlet and outlet vbeing so constructed that any of the well-known pipe threaded'connections may be utilized in connecting with the trap, and the inlet and discharge outlet being on the same horizontal plane with respect to the body portion.

'Another object of this invention is to so construct 'the trap that the mouth of the trap will be of the same size as its main body portion, and so that the trap will readily form its own seal wit-hout any partition, addition or removable parts connected therewith, excepting a screw-threaded removable cover secured to the top of the said body portion, which cover may be readily removed when it is desired to cleanse the trap. The foregoing and such other objects as may occur from the-ensuing description are attained by the construction, arrangement and location of the parts hereinafter more fully described, illustrated in the accomo panyi-ng drawings and particularly pointed 'ing the device embodying my invention in entirely with all movable parts and interior out in the claims appended hereto, it being understood that slight changes in the Jform, proportions and minor details of the constructlon may be resorted to without departmg from the spirit or sacrificing any of the advantages of the invention.

^ ln the accompanying drawings which form a part of the specification, it will be seen that:

Figure 1, is a view in side elevation show connection with a bath tu .Fig. 2, .is a perspective of my improved devife showing it in disconnected position, an

F ig. 3, is a central sectional elevation of the device shown in Fig. 2.

Similar characters .of reference are employed to designate corresponding parts throughout the several figures of the drawings.

In carrying out my invention as illustrated, it will be seen that the trap A. is connected to the waste outlet of a bath tub B, by a threaded pipe connection l, which is securely fit-ted to the threaded inlet 2, formed integral with the main body portion 3 of the. trap, at one side thereof, and diametrically opposite to said inlet is formed the outlet or dicharge member 4 of the trap, said outlet or discharge being integrally connected to the main body portion at the bottom of said body, and extending outward and upward at an angle of substantially forty-five degrees and terminating with a threaded portion 5 in the same horizontal plane with the inlet 2, said outlet being integrally connected with the body portion of the trap by anl integral web or extension 6 forming a part of the trap, and constituting a strengthening and reinforcing portion thereof. Fitted to the threaded portion of the outlet is a threaded pipe connection 7, which leads to and is connected with the waste pipe 8, leading to a sewer.

lt will be perceived that my improved trap is formed from a single piece of cast metal which may be coated with an suitable rust-prooic coating, but is pre erably formed from a single piece of galvanized cast-iron, and the top ofthe main body portion is screw-threaded and adapted to re. ceive a screwthreaded nickel-plated removable metallic Icover 9, provided with an annular portion extending beyond the vconnected at its bottom with an outlet v the event it should become clogged or partly body portion, which may be readily removed to permit access to the interior of the trap for cleansing purposes, and it will be also obvious that owing to the discharge outlet being connected at the bottom of the body portion on a horizontal plane with said bottom and extending at an angle upward and outward therefrom, access may easily be had thereto from the interior of the trap by a wire or other suitable means, for the purpose of cleansing or clearing ,said outlet, in

choked up from any cause whatever.

It will also be seen that the trap is selfsealing by the retention within the main body portion of a considerable volume of water which always remains therein between l the inner end 0f the outletportion and the lower end of the inlet portion, said volume of water being sucient to prolong the breaking of the seal' by evaporation thereof, and always serving to prevent the escape of foul sewer gas or air Vinto a room towhichthe fittings are connected and to protect the tra screw and cover from contact therewith.

wing to the precise construction of this trap, it will be readily obvious that since it I I 'dispenses with the action of movable parts,

partitions, and additions for its seal, and 1s providedwith a large main body portion formed at an angle with respect to *said body', that the trap is self-.cleaning which materially lessens `any liability of its discharge being clogged or otherwise interferred with.

While I have shown one mode of connecting my improved trap to a bathtub, it will be understood that any suitable or desirable method may be employed in making the required connections. v f

Both the inlet and outlet are provided on their exterior surface with a series of integral ribs 10, adapted to receive a suitable tool for holding the trap in a stationary position during the process of fitting the suitable pipe connections thereto.

.From the foregoing description, it will be readily perceived that I have produced a trapwherein the labor and expense of wiplng JointsV in attaching the inlet and outlet pipes thereto is entirely dispensed with, a

trap vwhich, is economical in production, which is self-sealing and self-cleaning, and` whichwill maintain and prolong an effective seal between the foul sewer gases which may accumulate in the waste pipes and the 'compartment in which the trap may be located, hence possesses marked advantages over the traps now employed in the art to whlchthis invention relates, and since it dispenses with all projections, partitions and recesses, it olers minimum resistance to the iiushlng, scouring iow of the waste-water.

Having thus described my invention, what I claim and desire to secure by Letters Patent is l. A sanitary self-sealing and self-cleaning trap for bath tubs, comprising a single casting of cast iron formed with a large main body portion, a threaded integral inlety at one side of the body portion, a threaded integral outlet at the opposite side of the body portion with its inner end connected in alinement with the bottom of said body and its outer end extending outward and upward at an angle with respect to said body portion and terminating on the same horizontal.

and terminating on the same horizontal plane with the inletand diametrically opposite said inlet, and an integral strengthening rib c'onnecting'the outlet to the body portion.

3. A sanitary self-sealing and self-cleaning trap for bath tubs, comprising a singlev casting of cast ironformed with a large main body portion of uniform diameter, a threaded integral inlet at one side of the body portion, a ythreaded integral v outlet at the opposite vside of the body portion with its inner end connected in alineL ment with the bottom of said body and its outer end extending outward and upward atan angle with respect to said body portion y and terminating on the same horizontal plane with the inlet and diametrically opposite said inlet, an integral strengthening rib connecting the outlet to the body "portion, and a screw-threaded removable cover fitted to the top of the body portion having a projecting annular rim extending beyond said body portion.

4. A sanitary self-sealing and self-cleaning trap for bath tubs, comprising a single casting of galvanized cast iron formed with a large cylindrical main body portion of uniform diameter and having a at top and bottom, a threaded integral inlet at one side of the body portion, a threaded integral outlet positioned diametrically opposite of said inlet with its inner end connected in aline-` ment with the dat bottom of the body portion and its outer end extending outward and upward at an angle with respect to said body portion, and terminating on the same horizontal plane in alinement with the inlet.

5. A sanitaryi self-sealing and, self-cleanintegral inlet at one side of the body por-` tion, a threaded integral outlet formed diametrically opposite said inlet with its inner end connected in alinement with the bottom of the body portion and its outer end ex-4 tendnng'outvv'ard and upward at an angle 10 with respect, tothe body portion terminating on the same horizontal plane in alinement with said inlet, and a screw-threaded niekel-plated cover provided with an annularimmextending beyond the outer surface 15 of the said body portion.
